This is highest specification sound level meter in the
Pulsar series of real time analyzers. It has real-time octave
and 1/3 octave band filters for a more detailed analysis
of the noise spectrum. The octave band filters cover the
range of 31.5 Hz to 16 kHz and the 1/3 octaves from 20 Hz
to 10 kHz and the meter also has real-time room noise evaluation
using NC curves.

This meter can be used as a standard Integrating Sound
Level Meter or switched into RTA mode to carry out Octave
or 1/3 Octave Band Analysis at the press of a single button.
Another button push starts the measurement going. This
meter has been designed to be very powerful, storing all
the parameters at the same time, while still being very
quick and easy to use.

As this meter has a single measurement span (no range selection
needed), it is suitable for measuring noise levels that vary
a great deal over time. A single span is also extremely beneficial
for octave and 1/3 octave band measurements. With a limited
span meter (one with manual range selection) you will often
get some bands going over the top of the range with others
are under-range. This is not the case with the P33 due to
the very wide dynamic range.

The price of the P33 is kept low by the careful use of the
latest technology. Microprocessors and Digital Signal Processors
(DSP) are now so powerful that they can carry out all the
functions required at a fraction of the cost of a few years
ago. This fact is reflected in the price of the P33 when
compared to other real-time sound level meters on the market.

The P33 is available on its own or as part of a complete
measurement kit that includes an acoustic calibrator, windshield
and a carrying case. The Type
2 version is indicated with a "-2" in the order
code and a kit with a "-K" in the order code.
